Conclusions:
The melting point determination of test chemical was done following OECD 102 and according to the method of Capillary/metal block.The test item starts decomposing at 252°C with colour change from yellow to green and turns black at 258.5 °C.The test was conducted in replicates and mean decomposition range was determine to be 252°C -258.5 °C at 972.7 hPa.
Executive summary:

The melting point determination of test chemical was done following OECD 102 and according to the method of Capillary/metal block.The test item starts decomposing at 252°C with colour change from yellow to green and turns black at 258.5 °C.The test was conducted in replicates and mean decomposition range was determine to be 252°C -258.5 °C at 972.7 hPa.
